[Podcast] Kernel Panic - Board on Fire ~~> #009: Ho Ho Ho VirtIO - QEMU, KVM, Barebox und wie sie zusammengefunden haben
Wir haben lange gewartet, um endlich wieder eine Weihnachtssonderfolge herausbringen zu können. Für diese Folge hat uns Ahmad mal wieder ein spannendes Thema mitgebracht, oder viel mehr einen Themenkomplex. Er erzählt uns nämlich wie sich, als Barebox in die oe-core Layer des Yocto Projekts gebracht wurde, die Gelegenheit ergeben hat spannendeende Dinge über Emulation und Virtualisierung mit QEMU und KVM und Paravirtualisierung mit VirtIO zu lernen.
Happy Holidays!
It's that time of year again. That time of the year in which the Pengutronix marketing team gets out the arts and crafts supplies and goes into recluse to come up with this year's hand crafted Christmas cards!
labgrid is going on a live tour!
labgrid makes it possible to remote-control embedded linux devices and to implement integration tests of a complete embedded Linux system on real hardware. The Pengutronix developers and other companies have been using labgrid as a centerpiece of their embedded software development infrastructure to great success for quite some time now.
Signed FIT Image Support for meta-oe (fitimage.bbclass)
FIT images provide a versatile way to bundle components used to boot embedded Linux systems, like the kernel, device tree, ramdisk, firmware, etc. They also support cryptographic signatures, making them ideal for verified boot setups. This blog post introduces the new fitimage.bbclass in meta-oe as an alternative to oe-core's kernel-fitimage.bbclass, with a clear focus on enhancing both versatility and signing support.
Pengutronix at Electronica 2024 in Munich
Electronica trade fair in Munich, Germany is just around the corner and Pengutronix is currently gearing up to showcase some of our latest topics and developments. You find us in Hall B4 Booth 102 (map).
Bringing Barebox into OE-Core (Yocto)
This blog post chronicles the multi-year journey to get Barebox accepted into OE-Core—from the early attempts to the eventual success in October 2024. Along the way, we’ll explore the technical hurdles we faced, the community discussions that shaped the process, and the improvements we added to both OE and Barebox.
The USB-SD-Mux is now FAST
We have been distributing the USB-SD-Mux with our partner company Linux Automation GmbH since 2019. This has enabled us to make work easier for many embedded developers and improve software quality. At the same time, technology is advancing: micro SD cards are becoming faster and USB-C is now established as the standard.
Managing Complexity with Open Source
A few days ago, something exciting happened: I revisited my very first embedded system - a 34 year old stepper motor controller, driving the telescope mount of the Public Observatory Rothwesten, which was built by me back when I was in class 12 in highschool. Comparing those embedded systems from back in the days with the recent industrial systems, it is impressive to see that the latter ones are not manageable any more without the use of open source software.
More Conferences in September: Yocto Project Developer Day and KiCon Europe
September 2024 brings a wide variety of conferences: Pengutronix will present talks at the ELCE, Linux Plumbers Conference and All Systems Go. Additionally we will attend two more conferences: The Yocto Project Developer Day in Vienna and the KiCon Europe in Bochum.
Pengutronix at All Systems Go!
This years All Systems Go! will take place on 25. and 26.09.2024 in Berlin. The ASG is a conference about low-level user-space topics. We are happy to contribute a talk about updating systems using RAUC and composefs:
